I am very interested to know what US buyers feel is an appropriate amount to charge for shipping anyway. Having seen $1.85 per item quoted, i thought it only cost about 50c to ship a chip??

I only charge $1.80 to ship first class airmail from the UK. This covers my shipping and handling cost and i charge no handling.

My rates for combined shipping are clearly stated on each item (70c extra per chip) and they are near enough at actual cost. Within the UK I only charge 95c + 45c.
